    That's because you loose low end power and torque with pretty much every CAI. That's why you never see the full dyno charts from K&N. They only show the charts in higher RPM ranges.

    Check to make sure all your hoses are clamped down and nothing is loose or disconnected. Vacuum leaks will bog you down.

    I have a 5.7 with the k&n intake and had the same issue. Wish I hadn't wasted my money. Even with the unichip and cat back exhaust, I still can tell there isn't as much low end torque. Will likely go back to the stock intake box.

    I have the TRD intake and have no such issues. I do not feel any low end torque loss (according to my butt-o-meter, haha).

    Actually, 4.6 is what convinced me to get a Tundra instead of Tacoma. Then reading through various forum pushed me toward 5.7. I think 4.6 is a pretty powerful engine as long as you don't go too high and big.

    I just had my k & n put in this past week and I do have the same issue. My truck rocks off the line at full throttle like a beast. But when it's reached max rpm and shifts the truck Boggs down almost to the point of near zero power. I had to let off severely to get it to react. It's extremely bad. I haven't checked all the lines for tightness but will do ASAP. I also added a dual flow master system today and still same issue. I have had numerous k & n products on others cars and none acted like this.

    ^^^ Calibrate your speedo. Thats due to the bigger tire size.

    This all comes back to upgrading to an after market CAI even though our Tundras com with a true CAI. I used a K&N drop in and called it day.
